No offence intended to the person who made MP4ui, but I definately don't recommend that anybody uses it.

Reason 1:
* I converted the AC3 to MP4 using Foobar 2000
* I open graphedit 9 and dragged in the AVI
* Delete the filters that appear after AVI Splitter
* I inserted a filter: Direct Show filters > File Source (Async) and choose the MP4 file
* Inserted filter: 3ivx D4 Media Muxer
* Inserted filter: File writer (give file the .MP4 extension)
* Connect the dots and hit play

Everything works a treat. A minute later you have a perfectly playable MP4 with 5.1 AAC and flawless Xvid encoded video. No need for MP4ui.

Reason 2:
The 4 movies I muxed using MP4UI are completely screwed up. If you extract the AVI, the index is gone. You can fix the index with AVIFIXED.EXE. (Search for it)
However, the AAC isn't recoverable. Graphedit crashes if you try to mux the AVI and MP4 together. It doesn't matter what you do [remove video from MP4 file, extract AAC to use by itself, stand on your head and whistle dixie...] you won't get the sound and video together again. Real Humpy Dumpty shit. Gotta rip the four damn movies again so I can extract the AC3 and run it through Foobar.

Go on... prove me wrong. Please. It'll save me a few hours.
